Re: svn diff of working copy file to unrelated branch file

Sorry, this is the e-mail client we have here at work. I'm not a fan of
it, but its what we have to use.

I want to thank you for solving the problem.
The svn diff syntax you provided works exactly as expected.

I would suggest adding this to the online subversion manual at
http://svnbook.red-bean.com/en/1.7/index.html.

"At this point, the wise thing to do is look at the changes carefully with
svn diff, and then build and test your branch."

It would be useful to mention the syntax of the svn diff command here so
that user's can see exactly how to do it.
I think it would save a lot of developers time.

Thank you very much. for your help.
I had spent an entire day trying to figure it out. Now it seems so easy
once you showed me.
Thank you.

I think this should work:

    svn diff --old=http://repository/branches/X/file.txt --new=file.txt

(i.e. the 2nd usage if you look at 'svn help diff')
